extensified

Miss extension methods from other languages? Python can have those too.

Installation

pip install extensified==0.3.0

Usage

from dataclasses import dataclass
from datetime import datetime

from extensified import extension_on


@dataclass
class Customer:

    name: str
    email: str
    created_at: datetime = datetime.now()


@extension_on(Customer)
class CustomerStringReprExtension:

    @property
    def rfc5322_email(self) -> str:
        return f'{self.name} <{self.email}>'

    @property
    def ldap_dn(self) -> str:
        email_domain = self.email.split('@')[1]
        return f'cn={self.name},ou=Users,dc={email_domain.replace(".", ",dc=")}'

    @property
    def vcard_name(self) -> str:
        surname = self.name.split()[-1]
        given_names = ' '.join(self.name.split()[:-1])
        return f'FN:{self.name}\nN:{surname};{given_names};;;'


customer = Customer("John Doe", "john@example.com")
print(customer.rfc5322_email)
print(customer.ldap_dn)
print(customer.vcard_name)

Limitations

Make sure that extension class is imported before its methods are used (i.e. import it in your init code).
super() can't be used in an extension class for now.
Type checkers won't understand what's going on and will complain about attributes missing.
